VIEW-EXHIBITING- APPARATUS.

To all whom it may concern:

Be it known that I, RICHARD R. VVHITiNG, a citizen of the United States,and residing at Norwood, Hamilton county, State of Ohio, have inventedcertain new and useful Improvements in View-Exhibiting Apparatuses; andI do declare the following to be a clear, full, and exact description ofthe invention, attention being called to the accompanying two sheets ofdrawings, with the reference characters marked thereon, which form alsoapart of this specification.

This invention relates to certain new and useful improvements in Viewexhibiting de- -vices of the kind where pictures, usually stereoscopicviews, are shown through viewglasses.

The invention concerns particular means and devices whereby a set orseries of such pictures is supported and moved in a manner that oneafter the other of them appears in position convenient for viewing.

The invention concerns also means whereby each one of the picturesof aset is connected to the general supporting devices. The views are eachprepared in a manner complementary to these particular support- 1ngmeans.

A feature of the invention is the particular arrangement of theoperating devices as well as of the views which permits the apparatus tobe used by two persons at the same time.

In the following specification and particularly pointed out in theclaims at the end thereof, will be found a full description of myinvention, together with its operation, parts and construction, whichlatter is also illustrated in the accompanying two sheets of drawings,in which Figure 1, shows the apparatus partly in side-elevation andpartly in crosssection.

Fig. 2, is a front-view of the apparatus partly in section.

Fig. 3, in part of a view similar to Fig. 2, shows a modifiedconstruction. Fig. 4, is a vertical section on line 4-4 of Fig. 3. Fig.5, in a view similar to Fig. 3, shows another modification. Fig. 6, isan enlarged edge-view of a part of this view. Fig. 7, shows at enlargedscale in a sectional view certain details of construction.

A shaft 10 supported at opposite ends in opposite sides 11, 11 of asuitable box, constitutes the means whereby a set of views aresupported. Power applied to this shaft, either manually or by means of asuitable Specification of Letters Patent.

the shaft and in a peripheral direction, that is in the plane in whichthey are carried around by the shaft. from the particular constructionof intermediate means whereby these arms are connected to shaft 10.These means consist substantially of a hub mounted upon shaft 10 and ofhinges provided on the periphery of this hub, one for each arm 13. Thehub consists of two disks 14, 14 spaced apart as shown and rigidlymounted upon shaft 10. The hinges indicated at 15 consist preferably ofwire-rods which are shaped to form parallel members A and a, connectedand spaced apart by intermediate parts of the rod. To the longer memberA of these hinges are secured the inner ends of arms 13, preferably asshown in Fig. 7, these ends belng curled around the rod and rigidlyconnected, by solder for instance. These hinges are carried by the hubmounted upon shaft 10, being connected to disks 14, 14 which constitutethis hub, their connection to these disks being at or near their edgesand is a pivotal or hinged one. It is by this particular manner ofattachment to the disks that the function of a hinged connection isimparted to arms 13 and this result may be obtained by the connection ofeither of the two parallel parts A or a of the hinges 15 to these disks.Thus for instance in Figs. 1 and 2 the connection is by the shorterparts a, a which are loosely mounted in oppositely located openings indisks 14.

In Figs. 3 and 4 the position of the hinges on the hub is reversed andthey are mounted in disks 14 by their longer part A which is nearestshaft 10. It will be perceived now that this manner of connectionpermits arms 13 to swing with reference to shaft 10 and independent ofthis latter, the pivot for this motion being constituted by hinges 15and more particularly by that particular one of their parallel partswhich is mounted on disks 14 and also nearest to shaft 10. Thus as shownin Figs. 1, 2, and 5, the short parts a a constitute the plvots for thismotion. In Fig. 3, the ends of the longer part A constitute thesepivots. In either case, the other parallel part of these hinges farthestfrom shaft 10, serves in conjunction with an additional member as ameans to limit this independent motion of arms 13, so that after thismovement is exhausted, said arms follow the shaft 10 and are positivelymoved by it. This additional member consists of a disk 16, rigidlymounted upon shaft 10. As shown in Fig. 2 this disk is mounted betweendisks 14. As shown in Fig. 3 it is mounted outside of these disks, butin each case its peripheral edge is inside of and below the outer one ofthe parallel parts of the hinges and with a space between it and theseparts. In each case the size of this space determines the extent of theindependent movement of arms 13 on shaft 10, and this movement islimited and terminates at once by contact of this particular hinge-partwith the edge of disk 16, this latter forming a positive stop. In Fig.5, this arrangement is modified by the omission of a separate disk 16,and in place of which disks 14 are each diametrically enlarged so thattheir edges constitute this stop and operate in conjunction with theouter parts of the hinges the same as disk 16 would otherwise do. InFig. 3, disks 14 are also slightly modified by being provided withflanges at their edges.

The views are provided with a sheath or pocket 17 closely fitted toreceive arms 13 and whereby, when slipped upon these arms, the views areheld in place. These pockets are formed by pasting a strip of suitablematerial, paper or fabric, upon the back of a picture. By preference Iuse two pictures, which are secured to each other, back to back, onebeing mounted upon the other one,

adhesive means being applied between them.

A strip of a width and length suflicient to receive arms 13 is leftdisconnected to form pocket 17 before alluded to (see Fig. (3). Thesepockets may be formed between the edges of a view as shown in Fig. 2, ornear or at one edge as shown in Figs. 5 and 6. In this latter case arms13 are provided with lateral extensions 18 upon which the views areslipped. This arrangement of the views results in a card 19, which hastwo' pictures, one on each one of its sides and whereby the View orpicture capacity in a given appae ratus is doubled, since two picturesare provided in a space which otherwise would be occupied by one only.At the same time the views are supported in a practical manner whichpermits convenient exchange, removal or attachment. The pictures may ofcourse be exposed to View direct and without the intervention of anyview-glasses. I prefer however to show them through glasses which may bestereoscopes as shown at 21. These glasses are mounted at the upper partof the sides 22 of the box, there being two of them, positioned oppositeeach other to direct vision inwardly and downwardly.

23 is a stop so located as to intercept the cards when they are moved byrotation of shaft 10. The engagement is with the extreme end of arms 13and is only a limited one, the object being to retard the cardstemporarily to permit observation of the picture on one side thereofwhich picture may be viewed through one set of the viewglasses, those onthe left, with reference to Fig. 1.

The uninterrupted motion of shaft 10, acting by means of disk 16 uponthe hingemembers, sets up a spring-action with respect to arms 13,whereby, as soon as the end of an arm 13, has slipped out from understop 23 and become free, the particular arm together with a card carriedon it, is at once thrown over to the opposite side (see dotted lines inFig. 1) until the outer part of the hinge of this arm comes again incontact with the edge of stop-disk 16. The arm after its forciblerelease occupies now an angular position similar to the one it occupiedbefore but on the opposite side and the picture on the other side of thecard on this arm may now be seen through the other view-glasses. It willnow be understood that first the picture on one side of a card 19 isviewed through one of the glasses, after which the picture on the otherside of the same card is viewed through the other glass, there beingalways a picture in position for viewing under each one of theview-glasses. Two persons may therefore use the apparatus at the sametime. The space below these glasses and between them is always clearbecause each card after its forcible release from stop 23 flops clearover to the other side. The spring-action before alluded to may be dueto the material of which arms 13 are made, which material may beresilient metal. It may also be due to the torsional strain set up inthat'part of the hingemember to which arms 13 are rigidly connected. Itmay also be due more or less to the joint action of these agencies.

Stop 23 may be secured to any available part within the box. It issecured here to the usual division or septum 24 which divides thestereoscope inside and which in this case is sufficiently extended forthe purpose.

Light may be admitted through glasspanels 25 in top, or sides or both.

In Figs. 1 and 4, the hinges and the armson them are shown withconsiderable space between them, and in Figs. 2, 3 and 5, only thesearms which occupy extreme positions are shown and all intermediate onesare omitted to render the drawings clearer. In reality these hinges andarms are contemeeasn plated to be much closer together and about asindicated in Fig. 7.

Having described my invention, I claim as new:

1. In a view exhibiting apparatus, the combination of a shaft,yieldingly attached arms carried thereby and each adapted to support twoviews arranged back to back, means to rotate this shaft with the arms, astop located in the path of these arms adapted to temporarily retardthem one after the other to hold one of the views carried thereby inposition for viewing a view-glass through which this view may beobserved and an additional view-glass to observe the other view on thisarm after this latter has been released from the stop.

2. In a view-exhibiting apparatus, the combination of a shaft, means torotate it, arms of elastic material adapted to interchangeably supportpictures hinged to it there being an arm for each picture, and a.rigidly connected stop located in the path of these arms and adapted toengage them temporarily in a manner to produce a spring resistedretardation in the arms whereby a retarded arm, after released by reasonof the movement of the shaft, is caused to move out of position,independent of the motion derived from the shaft, to expose a picturecarried on the arm following it.

I11 a .view exhibiting apparatus, the

combination of a shaft, means to rotate it,

a hub on it and arms of elastic material adapted to support viewsyieldingly connected to this hub in a manner to be capable of a limited,independent movement with reference to the shaft so that one pictureafter viewed may move out of position to expose the one following it,independent of the motion derived from the shaft.

4:. In a view exhibiting apparatus, the combination of a shaft arrangedto be rotated, a hub on it, arms adapted to support views, a hinge foreach arm consisting of two spaced, parallel members A, a, to one ofwhich the end of an arm is rigidly attached, while by means of its othermember each hinge is pivotally mounted upon the hub and whereby thesearms become capable of a certain movement independent of the shaft andmeans adapted to co-act with and en- &

gage one of the hinge members to limit this movement of the arms.

5. In a view exhibiting apparatus, a series of fiat arms of spring metaladapted to support views interchangeably, rotary supporting means towhich each arm is rigidly attached at its inner end and all mounted forrotation, and a rigidly connected stop immovably supported in the pathof the outer ends of these arms and adapted to temporarily retard themby engaging these ends.

6. In a view-exhibiting apparatus, the combination of a shaft arrangedto be rotated, two disks mounted thereon with a space between them, ahinge-rod supported at its ends between these disks, flat arms of springmetal adapted to support views one rigidly attached to each of thesehinge-rods and between their ends and a stop located in the path of theouter ends of these arms and adapted to temporarily engage them.

7. In a View exhibiting apparatus, the combination of arms, viewsprovided with pockets on their rear side fitted to receive these arms soas to support the views and means supported for rotation upon whichthese arms are mounted.

8. In a View exhibiting apparatus, the combination of arms, view-cardsformed by two pictures, secured back against back except where a pocketis reserved between them fitted in width to receive the arms, to supportthese cards and means to support these arms.

9. A new article of manufacture consisting of two sheets of paper ofcongruent outline, each with a picture on one side and pasted togetherso as to be connected to each other at their blank sides all aroundtheir edges and between them, with exception of an elongated, narrowspace extending from one of the edges inwardly and where no paste isapplied so as to leave a pocket which permits insertion of means forsupporting the card.

In testimony whereof, I hereunto aiiix my signature in the presence oftwo witnesses.
